HMC541LP3

HMC541LP3 / 541LP3E v01.1005 10 dB GaAs MMIC 1-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, DC - 5 GHz 5 Typical Applications Features ATTENUATORS - SMT The HMC541LP3 / HMC541LP3E is ideal for both RF and IF applications: Cellular Infrastructure ± 0.2 dB Typical Step Error Low Insertion Loss: 1 dB High IP3: +50 dBm ISM, MMDS, WLAN, WiMAX, WiBro Microwave Radio & VSAT Test Equipment and Sensors LETE Functional Diagram Single Control Line TTL/CMOS Compatible Control Single +5V Supply 3x3 mm SMT Package General Description The HMC541LP3 & HMC541LP3E are broadband 1-bit GaAs IC digital attenuators in low cost leadless surface mount packages. This single positive control line digital attenuator utilizes off chip AC ground capacitors for near DC operation, making it suitable for a wide variety of RF and IF applications. Covering DC to 5 GHz, the insertion loss is less than 1 dB typical. Attenuation accuracy is excellent at ± 0.2 dB typical step error. The attenuator also features a high IIP3 of +50 dBm. One TTL/ CMOS control input is used to select the attenuation state. A single Vdd bias of +5V is required.
